Precautions
Your MU10 will give you years of reliable service if you follow the simple rules given
below:
■ LOCATION
Do not expose the instrument to the following conditions to avoid deforma-
tion, discoloration, or more serious damage.
• Direct sunlight (e.g. near a window).
• High temperatures (e.g. near a heat source, outside, or in a car during
the daytime).
• Excessive humidity.
• Excessive dust.
• Strong vibration.
■ POWER SUPPLY
Turn the power switch OFF when the instrument is not in use.
This instrument runs from either an optional AC adaptor or batteries:
(When using AC adaptor) Use ONLY a Yamaha PA-3B, PA-1207 or equiva-
lent AC Power Adaptor to power your instrument from the AC mains. The
use of other adaptors may result in irreparable damage to both the adaptor
and the instrument.
An AC adaptor should be unplugged from the AC outlet if the instrument is
not to be used for an extended period of time.
Unplug the AC adaptor during electric storms.
Avoid plugging the AC adaptor into the same AC outlet as appliances with
high power consumption, such as electric heaters or ovens. Also avoid using
multi-plug adaptors since these can result in reduced sound quality, operation
errors, and possibly damage.
Always unplug cables by gripping the plug firmly, not by pulling on the AC
adaptor cable.
(When using batteries) When the batteries run down, replace them with a
complete set of new batteries. NEVER mix old and new batteries, and
different kind (e.g. alkaline and manganese) at the same time.
To prevent possible damage due to battery leakage, remove the batteries from
the instrument if it is not to be used for an extended period of time.
